LUBRIQATOR.

i, Naeoaml.

i 'To a/ZZ whom, it may' cora/caw@` Beit known that I, ALBERT L.MATTn'soN,a

citizen ofthe UnitedStates, residing at`Bat- 4'tlecreelL in the countyvof'Calhounand State of Michigan, have invented a certain new and usefulLubricator, of which the following is `a specication, reference beinghad therein to 'the accompanying drawings.

be associated with Athe steam-supply pipe to convey o il directly to thecylinder and which is capable of being easily regulated Vto raise thelubricant to the desiredtemp'erature and maintain it in aproperly-heated condition, so

that the same will be eifectivelyliquefied inl the coldest weather, thusinsuring the feeding of the-oilin proper condition at all times to thecylinder.

' Thev invention relates particularly 4to the construction of thelubricator, the manner in which the heating of the oil and itsmaintenance in a properly-heated condition is con-l trolled andregulated, and in connection therewith the means by -which the water ofcondensation is supplied to the oil-reservoir and sight-feed tu be andmaintained atl the requisite temperature, and in the manner in which theoil is delivered from the lubricator and its liquefaction maintained upto the instant of its discharge from the lubricator.

A further objectof the invention is to provide, in connection withacondensation and oil-discharge pipe, a steam-heating chamber for theoil-reservoir and meansl for regulating the supply of steam to saidchamber and also cutting off said supply altogether. f

' With the above and other objects in View, the nature of which willmore fully appear as' the description proceeds, the invention consistsin the novel construction, combination, and arrangement of parts, ashereinafter fully described, illustrated, and claimed. In theaccompanying drawings, Figure 1 is a diametrical longitudinal sectionthrough a lubricator embodying the present invention. Fig. 2 is asimilar section taken at right angles to Fig. 1. Fig. -3is atop planView of the lubricator. Fig. 4 is a'cross-section-through thelubricator, taken in line with the oil-discharge tube.

lThe lubricator-contemplated in this invention comprisesan'oil-reservoir 1, which is preferably of cylindrical form, as shown,although any desired shape may be given thereto. This reservoir incarrying out the present invention is provided in its upper end' with acondensation-chamber v2 and in the bottom with an automatic steam-heating lchamber 3, the said chambers practically covering the entirecross-sectional area of the top and bottom of the reservoir, as shown.

Extending between the chambers 2 and 3 is a combination condensation andoil-dischargel pipe 4, which communicates with both of said chambersand-is preferably cast or formed integrally therewith and in one piecewith the body of the reservoir.

'Thereservoin the Walls of the chambers 2 and 3, and the condensationand oil-discharge pipe 4, above referred to, are all made in one pieceunder the preferred embodiment of this invention,

A globe-shaped condensation-chamber 'extends upward from the top'of vthereservoir and communicates at its bottom with the internalcondensation-chamber 2, 'as'shown, and a condensationt1p1be 6extendsfrom the upper end of the pipev 4 upward into the upper portion'o f the chamber 5. L

7 represents the oil-pipe, which connects at its lower end with thevalve-casing 8, located adjacent to the lower end of the' reservoir andcarrying.- the feedcontrol needle-valve 9 and the drain-valve 10. Theopposite upper end of the oil-pipe is arranged near the top of thereservoir to receive the oil as it is raised by the water ofcondensation and overflowsinto said pipe. f

Communicating with the upper'portion of the reservoir is anoil-dischargepipe orftube 11.V This tube leads from thefcentral pipe 4outward through the'reservir, where it connects With a coupling 12,which receives the upper, end of 'a sight-feed glass or tube 13, thelower end of whichconnects with the valvecasing 8, above' referred to.

14 designates an oil-dropping tube or nozzle extending from thevalve-casing 8 upward into the sight-tube 13.

15representsthe tube which receives the water of condensation from thechamber 2 and carries the same into the bottomof the oilreservoir 1, thesame being controlled 4by a Water-admission valve 16, located at theupper end thereof, as shown in Fig. 1. In the IOO IIo

bottom of the reservoir, beneath the pipe 15, is arranged a drain-plug17.

At one side of the reservoir 1 is arranged an oil-gage 18, whichcommunicates with the top and bottom portions of the reservoir andindicates the oil-level therein. The reservoir is also provided with anoil-filling plug 19.

2() designates a union at the bottom of the reservoir, by which thelubricator is connected into the steam-supply pipe leading from theboiler to the cylinder or steam-chest, said union communicating directlywith the steamheating chamber 3 and the pipe 4.

The oil in the reservoir is heated by the steam in the heating-chamber3, which is advantageously located in the bottom of the reservoir,covering the entire bottom thereof and draining itself automaticallyinto the steamsupply pipe, the walls of said chamber being thusconstantly maintained in a highly-heated state.

Water is supplied to the oil-reservoir and sight-feed glass through thecombination condensation and oil-discharge pipe 4, through which the oilalso passes on its way to the steam-supply pipe and cylinder of theengine. The oil does not passoutside of the lubricator-body eXcept as itpasses through the sightfeed glass` so that it is impossible for the oilto become chilled on its way to the cylinder. This makes it practicableto use the heaviest oils inthe coldest weather.

By locating the heating-chamber in the bottom of the reservoir the heattherefrom riseseasily and rapidly. A great advantage of the inventionalso lies in the fact that it requires only one pipe to furnishcondensation for both the oil-reservoir and the sight-feed glass,heating the water of condensation and providing means for conveying theoil to the steam-supply pipe and cylinder without any liability of theoil becoming chilled on its way.

The pipe or tube 4 where it extends through the chamber 3 is providedwith a small hole 21, and said hole is controlled by a hand-operatedvalve 22, 'which provides for cutting on communication between the pipe4 and chamber 3, the stem of said valve passing through the chamber 3,as shown in Fig. 2. When the valve 22 is opened, the chamber 3 fillswith steam and raises the oil to a scalding heat in a very short spaceof time. By adjusting said valve the /degree of heat may be varied tosuit conditions. In very hot weather the valve 22 may be entirelyclosed, leaving the lubricator as cool as the ordinary lubricator.

It Will be observed that the lubricator is simple in construction andfree from narrow and tortuous passages, an objection to whichl manylubricators are open.

Having described the invention, I claim as new- ,l

1. Alubricator comprising an' dil-reservoir; a steam-heating chamberlocated injthe bottom thereof; a condensation and oil-discharge pipeextending through the reservoir and steam-heating chamber, and means forcontrolling communication between the said pipe and steam-heatingchamber.
